It may have changed but when i spoke to him a few days ago he said you could put orders in on sunday after yom tov also. The deal is live on t-mobile's end till the 30th.
I put my order in yesterday the salesman called just for the social number. And then emailed a confirmation of the plan and the phones. He said we will a add internet to the lines after the phones come. Besides for him communicating slowly by email, it was decent experience. Also, he would not ship the phones to 2 separate addresses. I ordered 6 S4's and one Note 3 so instead of shipping the S4's to FL and the N3 to NY he said when ups emails us with the shipping notice we should call him and he will divert the package to NY. Im a bit concerned that it will ship to FL, but we shall see.
